According to your system behavior it seems the operating system was installed using Legacy boot. This is an older Intel® NUC Kit and UEFI Boot was not the default option in the BIOS.
Hard Disk Drives equal or with more than 2TB requires UEFI boot enable.
If you have Windows® 7, I recommend you to get into the BIOS, enable UEFI and Legacy boot, enable USB Legacy. Then, while the NUC is starting up, keep tapping F10 and select UEFI – USB Windows® 7 Bootloader and reinstall Windows® 7 operating system.
Thanks for the reply. AFAIK I thought UEFI boot was only if you wanted to boot from a drive greater than 2TB? My boot drive is a 60GB SSD. It's just my media files that I have on the USB 3.0 drive. Not sure why UEFI boot would affect just the drive on the USB 3.0 port when it's OK on the 2.0? Bit reluctant to go back to Win 7 TBH. 10 runs smoothly.
That said I've come across another potential issue in that the DN2820 cannot support DTS-HD or Dolby True-HD on passthrough due to PAP (protected audio path) restrictions. I believe something like OpenElec doesn't have this restriction.
Based on your comments I managed to convert my SSD from MBR to GPT, created enough free space at the start of the disc for new system and UEFI partitions, and created the boot entries. I followed these instructions.
As a result I now have the NUC booting UEFI with no legacy boot options and only UEFI boot in the bios.
I uninstalled the drivers for the USB controller and xHCI and rebooted just in case!
The USB 3.0 4TB external drive still misbehaves on the USB 3.0 port. I start to copy across the network and after a few MB the copying stops. On the NUC UI the drive is unresponsive and occasionally not there at all. No problem whatsoever on the USB 2.0 ports nor on my UEFI desktop W10 with USB 3.0 ports. I've tried copying to the drive from a remote PC and using the share on the NUC, and vice versa. Still the same.
Any other thoughts?
PS. On the NUC, this error pops up .
It is better to keep Legacy boot (Boot tab) and USB Legacy (Devices tab) options enable. Many devices in the market are still working as Legacy.
In order to narrow down, verify if you have the latest BIOS version 0052.
Thanks so much for trying to get to the bottom of my USB 3.0 issue.
Yes, I am on 052.
I changed the USB to Legacy and the Boot as well as you suggested. The problem persists.
The same USB 3.0 drive when plugged into my Desktop PC with USB 3.0 and WIndows 10 64 bit behaves absolutely fine and has done for a year or more.
I am stumped and disappointed it's not working as it should.
I think I've exhausted my fault finding capabilities! This is so frustrating!
Here is a video of what happens when I try to copy a 3GB file from my SSD (boot) to the USB 3.0...
After this copy failure the drive becomes unresponsive and I have to reset it to access it again. Reads are unaffected.

I regret the inconvenience. According to your troubleshooting, it seems your Intel® NUC Kit DN2820FYKH is faulty. I recommend you to get in touch with Contact Support and request a RMA of your device.
